Drilling fluid system name

Capacity release fluid

Matching core finishing agent

Double effect solid acid breaker HWNA    Channel dredging agent HWCD    Antihypertensive drainage aid HWDA    Water proof lock agent HAR    High temperature corrosion inhibitor HWSJ

System characteristics

1、Reduced pressure production perforating liquid: It has pore channel dredging, antihypertensive assisted drainage, reducing water saturation and preventing water lock;

Acidification capacity release liquid: It has double-effect gel breaking, pore clearing, pressure-relieving drainage, reducing water saturation, changing reservoir wettability and preventing water lock.

Application situation

The system has been successfully applied to more than 10 horizontal wells/directional wells in Wenchang 9-2/9-3/10-3 and other low permeability and ultra-low permeability gas fields, which has achieved far superior production allocation.
